Lattice UC120 USB-C PD PHY driver

This is the clean-room implementation of Lattice UC120, a long-abandoned USB-C PD PHY chip that exclusively used on Lumia 950 and 950 XL. It is actually a specialized iCE40 FPGA programmed with a USB-C PD PHY logic bitstream.

Lattice stopped supporting this chip long time ago, and there is few documentation available on the Internet. They even removed references to UC120 in their website.

Status

This driver only serves as the PHY portion and needs to be used with upper USB-C controller drivers. Currently it can act as a "drop-in" replacement for the stock ice5lp_2k.sys driver in Windows Phone firmware except for manufacturing calibration features.
